Question

the circumference of a circle is 44 m. find the area of the circle

Answer 1

2πr = 44
r = 44× 7/22 ×1/2 = 7 m
area = π r ² = 22/7 × 7 × 7 = 154 m²

Answer 2

here is your answer

given :

circumference of a circle = 44 cm

given :

circumference of a circle =
$2\pi \: r$
$2\pi \: r \: = 44$
$2 \times \: \frac{22}{7} \times r \: = 44 \\ r = 44 \times \frac{7}{22} \times \frac{1}{2} \\ r = 7cm$

area of a circle = pi(r)^2

area of the circle = 22/7*(7)^2

= 154 cm^2
